A vector is “Any animal capable of transmitting the causative agent of human disease or capable of producing human discomfort or injury, including but not limited to: mosquitoes, flies, mites, ticks, other arthropods, and rodents and other vertebrates”. (California Health and Safety Code Section 2002(k)).

The District’s objectives are to keep vector populations below levels where they become a serious public health problem, leading to an outbreak of disease.

By monitoring environmental conditions that can increase risks for vector-borne disease, the Coachella Valley Mosquito and Vector Control District can help protect the overall health of the public.
